{"version":"1.0","type":"rich","title":"Vega-Lite API Temperature Line Chart","description":"This example shows a line chart of San Francisco weekly temperatures over time, using a clean dark-on-light design with tooltips displaying exact values. The visualization is built entirely with the Vega-Lite API, which programmatically constructs a specification for a single line mark with encoded x and y fields from CSV data loaded via `d3.csv`. The code registers Vega, Vega-Lite, and the Vega-Lite API, then renders the chart as SVG fitted to the viewport, with custom axis and label styling from a shared config object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a5e0d215429d44e9a015b6012fccf7b2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
